TO ALL WHOM IT MAY CONCERN:

Be it known that-I, JOHN LYNbH, of Columbia, in the district ofRichland, and State of South Carolina, have invented a newand usefulImprovement in Adhesive Plasters; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable those skilled in the artto make and use the same,

reference being had to the accompanying drawings, forming part of thisspecification;

' This invention relates to a new and improved method of formingstrengthening-plasters, whereby they are rendered much more useful andeffective than they have hitherto been.

And it consists in attaching to the backs of such plasters one or moresprings,-stays, or flexible rods, or bars, which not only prevent theplaster from crumpling or wrinkling, but serve as additional support tothe muscles, as will be hereinafter more fully described. Figure 1represents the face of the plaster, and

Figure 2 represents the back, showing the springs or flexible'bars, andthe manner in which they are attached;

l Similar letters of reference indicate corresponding parts.

A is the adhesive material, which is spread upon theleather or cloth. 13represents the leather or cloth.

0, represents the springs. or stays, which may be made of any flexiblematerial, as whaleboneewood, or

metal, or of any equivalent substance.

These springs may be made to pass across the back of the plaster in anydirection, either longitudinally, transversely, ordiagenally, but Iprefer the method seen in the drawing as being the most eflectual forthe purpose intended.

D represents pockets, formed of pieces of tape, or other suitablematerial, in which the ends of thesprings are secured, so that, bybearing against the bottoms of the pockets, the plaster willat. alltimes be extended and prevented from wrinkling or crumpling.

It is a mooted question among medical men whether the benefitderivcdfrom the application of an ordinary plaster is not mainly owingto the mechanical support which it gives to the muscles.

Whether it be so or not, such support is vastly increased by the springsor stays which I attach to the plaster.

E represents loops, through which the springs, rods, or stays pass.

I do not confine in self to an articular number of s rings or sta s norto an articular manner of attaching or securing them to the plaster.

I claim as new, and desire to secure by Letters Patent- 1. The springsor stays C, or their equivalents, in combination with an adhesiveplaster, substantially as and for the purposes herein shown anddescribed.

'2. Attaching one or more springs or flexible stays, rods, or bars toadhesive plasters, for the purposes describcd.
